On a related note, I encourage Beyond Awesome (or delegate) to comb through the last 3-4 years of articles and feature the best ones on the blog. There's no need to start from scratch. I'm sure the community would be willing to help you identify the gems.
I'll start since I combed the Articles archive a year ago or so. Here's my list of greatest hits from 2015 that can probably be repurposed, some of which did appear on the blog before it went dormant, I think. Probably worth focusing on combing 2016-2017 rather than going further back.
Light-Hearted Strategic Fun:
=================================
The 10-Word Card Summary Challenge (OP is not updated. Whole thread is good.)
The Haiku Card ChallengeI would LOVE to see responses in these threads made into blog posts. Ten cards from the 10-word card challenge or ten haikus. Something like that. And these threads are lacking post-Adventures posts.
Strategy:
=================================
Engine Economies and the Limitations of Money Density (WanderingWinder, March 2015)

Also partly outdated, but I liked the idea.
